TERMINAL APPARATUS, BASE STATION APPARATUS AND METHOD

WIPO Patent Application WO/2017/078148

A1

The objective of the invention is to efficiently control a cell that uses an allocated frequency band, a non-allocated frequency band or a shared frequency band. A terminal apparatus that communicates with a base station apparatus comprises a reception unit that receives an upper layer signal including a discovery signal (DS) setting for a certain frequency and information indicating whether a partial subframe is set in a cell corresponding to the frequency. If the DS setting includes a CSI-RS setting and further if the transmission of the DS overlaps the transmission of PDSCH and/or EPDCCH of the partial subframe, the reception unit measures a reference signal reception power and a reference signal reception quality on the assumption that the DS is not transmitted in the partial subframe.
